I have copied the solver "channelFoam" and renamed it to "my_channelFoam". i am working in my user space and not in the installattion space of OpenFOAM.
The error appears when I try to run wmake to compile the new solver.

I have seen in other related posts that the new solver should appear in the $FOAM_USER_APPBIN. If I go to this directory, I can't find anything. The /bin/linux64GccDPOpt has been created but it is empty.

I precise that I am working on a college computer so that I do not have sudo rigths. I tried to set the correct environnement variables using the "source .bashrc" but I still get the error.

From the error message in the terminal window the problem may come from a library problem but I can't solve it.

It's been some time I am working on it and I would be grateful if someone can help me.
